Description

Pedal control lavatory automatic flushing device

The utility model relates to a kind of improved plumbing hygiene utensil, particularly is applicable to a kind of pedal control lavatory automatic flushing device in flushing lavatory.

The manual flusher in original mechanical type lavatory is to adorn a float valve in water tank, and water is annotated certain water level, and ball float floats, and closes float valve, manually flushing after the excrements.Also have regularly flusher of a kind of lavatory, the water in the water tank is annotated certain water level, the flushing that just discharges water automatically, and the time interval of each water filling is identical.

The purpose of this utility model is with the manual flusher in existing lavatory, and regularly flusher is improved to pedal control lavatory automatic flushing device, i.e. health is economized on water again, joint power, saving fund.

The utility model is made up of water tank, float valve, pedal, switch-box, and the fixed point of pedal is connected with the loose-leaf that fixes on the ground, and the other end is connected with the lower end of short slide fastener, and the right-hand member of lower link is connected with the upper end of short slide fastener; The fixed point of left end with fixing on the wall to give embedded part hinged; About between moving point be connected left end and the hinged place of vertical connecting rod lower end of pull bar during the upper end of long slide fastener is connected in, the fixed point of middle pull bar right-hand member and to be fixed in the lower support of switch-box hinged with the lower end of long slide fastener; About between moving point and the switch lower end of drawing hinged, the upper end of switch lever is connected with foot switch, switch-box and water tank are all fixed on the wall, the upper end of extension spring is connected on the switch-box, the hinged place of pull bar and vertical connecting rod during the lower end is connected in, the fixed point of upper connecting rod right-hand member is hinged with the upper support that is fixed in switch-box; Left end with hang down that the water outlet valve rod in the outlet valve is connected in water tank; About between moving point and vertical connecting rod hinged.The foot switch left end is fixed on the switch-box, and is communicated with float valve by the water pipe loose joint; Right-hand member is communicated with running water pipe.

The utility model is applied to collective's water closets such as hotel, unit especially, the manual flusher in original mechanical type lavatory, some people operation flushing machine that do not lift a hand after going to toilet, wash the lavatory, cause excrements to increase, closet stops up, smelly water is excessive, stinks to high heaven; Another kind of lavatory is flusher regularly, concentrates when going to toilet personnel, and institute fixes time and just seems longer, has little time flushing, and the smell of urine is smelly unpleasant in the lavatory, and when the no one used the lavatory, it still continued to cause very big waste in the flushing that regularly discharges water.As long as the utility model has the people to go to toilet, set foot on pedal, promptly begin in water tank water filling and close to certain Water level ball float, after pedal was left in upward intact lavatory, the flushing that just discharges water had automatically been accomplished that the people walks promptly to dash, and does not accumulate and urinates and defecates, and is unlikely to obstruction, does not stay stink.The utility model is compared with the manual flusher in lavatory, and or else personnel selection starts to operate flushing machine; Compare and in time to wash with lavatory timing flusher, do not stay stink again, when nobody goes to toilet, just no longer discharge water and dash, can save a large amount of and valuable water.The utility model is empty in the water tank when unmanned stool or urine, effective like this solved ubiquitous because of water tank inner float ball valve, the outlet valve running water phenomenon that is not closed completely.Solve raw water box inner float ball valve duration of load application length and often damaged problems such as frequent replacing.Maintenance cost and element expense have been saved.The utility model accomplishes that the people walks promptly and dashes, i.e. health is economized on water again, joint power, saving fund.

Below with reference to accompanying drawing the utility model is described in further detail.

Accompanying drawing is the utility model structural representation.

With reference to accompanying drawing, the utility model is made up of water tank 16, float valve 15, pedal 1, switch-box 12, and the fixed point of pedal 1 is connected with the loose-leaf that fixes on the ground 22, and the other end is connected with the lower end of short slide fastener 2.The right-hand member of lower link 3 is connected with the upper end of short slide fastener 2; The fixed point of left end with fixing on the wall to give embedded part 23 hinged; About between moving point be connected with the lower end of long slide fastener 4.The left end of pull bar 7 and the hinged place of vertical connecting rod 13 lower ends during the upper end of long slide fastener 4 is connected in.The fixed point of middle pull bar 7 right-hand members is hinged with the lower support 8 that is fixed in switch-box 12; About between the moving point and the lower end of switch lever 6 hinged.The upper end of switch bit bar 6 is connected with foot switch 10.Switch-box 12 and water tank 16 are all fixed on the wall, and the upper end of extension spring 5 is connected on the switch-box 12, the hinged place of pull bar 7 and vertical connecting rod 13 during the lower end is connected in.The fixed point of upper connecting rod 14 right-hand members is hinged with the upper support 11 that is fixed in switch-box 12; Left end is connected with the water outlet valve rod 17 that hangs down in 16 li outlet valves 18 of water tank; About between moving point and vertical connecting rod 13 hinged.Foot switch 10 left ends are fixed on the switch-box 12; And be communicated with float valve 15 by water pipe loose joint 21; Right-hand member is communicated with running water pipe 9.Leader 19 upper ends are communicated with outlet valve 18; End is communicated with pan 20.Pedal 1 places pan 20 1 sides, the position that when using pan 20, can tramp with one's feet, and pan 20 opposite sides can be increased to identical with height after pedal 1 depresses with cement, ceramic tile or other material according to different situations.The utility model is work like this: when using pan 20, ride on pedal 1.The short slide fastener 2 of pedal 1 drive, lower link 3, long slide fastener 4, middle pull bar 7, a perpendicular position bar 13, upper connecting rod 14 move down, and extension spring 5 stretches, and the water outlet valve rod 17 of while upper connecting rod 14 right-hand members falls to closing outlet valve 18; In pull bar 7 move down and drive foot switch 6 and move down, foot switch 10 is opened, tap water by running water pipe 9, foot switch 10, water pipe loose joint 21 to float valve 15 to water tank 16 water fillings.Annotate certain water level when the water of water tank, float valve 15 floats closes, and tap water stops to water tank 16 water fillings, and the utility model mechanism position shown in the drawings is exactly the position of this moment.After an action of the bowels, pin leaves pedal 1, and extension spring 5 withdrawals drive simultaneously on long slide fastener 4, lower link 3, short slide fastener 2, the pedal 1 and retract the position; Move on the moving switch lever 6 of shipper pole on the middle pull bar 7 and close foot switch 10; Move on the moving upper connecting rod 14 of shipper pole on the vertical connecting rod 13, mention water outlet valve rod 17, outlet valve 18 is opened and is discharged water, and water flows into pan 20 through leader 19, washes away ight soil.Along with the water level of water tank 16 reduces, float valve 15 falls to opening, and gets ready when using next time.The utility model can be used for pan, water closet, urinal, in like manner also can be used for excrement groove, makes the pond for a short time.This use is novel also can change a social system on the basis of the manual flusher in original lavatory, timing flusher, so that economize on the use of funds.
